摘要：

In order to carry out the research on the modification of concrete creep prediction model, the creep test and numerical simulation of concrete under different stress levels were carried out. Through numerical simulation, the creep characteristics of concrete under tensile and compressive stress, cyclic stress and biaxial stress were studied. For the low accuracy of the creep prediction model CEB/FIP 1990, the useful creep coefficient correction value was given based on creep characteristics of concrete under different stress levels. The results show that the numerical simulation method in this paper provides a new idea for the modification of concrete creep prediction model. © 2017, Materials Review Magazine.
